VIBRATION OF NEARBY STRUCTURES INDUCED BY HIGH-SPEED RAIL TRANSIT

Oral Defense by Pei-wen ChenSonny Astani
Department of Civil and Environmental EngineeringAbstract:This dissertation is centered around the need for analyses concerning ground borne vibration caused by high speed rail transit. As the speed and weight of the trains increase, the vibrations caused by the transportation system can affect the local environment and economy. Selected for a case study is the Taiwan High Speed Rail (THSR); it's readily available geotechnical and structural data and make it an ideal case for a detailed analysis. TheTHSR route traverses through densely populated areas of Western Taiwan where modern computer technological institutes are located. The ground borne vibration has affected that industry and caused costly relocation of the factories. The work herein focuses on the vibration generated by deeply embedded piles of the elevated track while most previous analyses were based on ground surface induced vibrations. It is shown that the soil-structure interaction effect of a resonant bridge can contribute to amplify the vibration at higher speeds.
